WARNING
Playing loud music in a ship can hinder your ability to hear traffic and permanently damage your
hearing. We recommend listening at low or moderate levels while driving your boat. B52 accepts
no liability for hearing loss, bodily injury or property damage resulting from the use or misuse of
this product.
IMPORTANT
To get the best performance from your B52 BMP-4004 Series amplifiers, we strongly
recommend that installation be entrusted to a qualified professional. Although these instructions
explainhowtoinstallB52BMP-4004Seriesamplifiersinageneralsense,theydonotshow
specific/installationmethodsthatmayberequiredforyourparticularvehicle.Ifyoudonothave
thenecessarytoolsorexperience,donotattempttheinstallationyourself.Instead,pleaseask
yourauthorizedB52caraudiodealeraboutprofessionalinstallation.
INSTALLATION WARNINGS AND TIPS
• Alwayswearprotectiveeyewearwhenusingtools.
• Turnoffallaudiosystemsandotherelectricaldevicesbeforeyoustart.Disconnectthe(-)
 negativeleadfromyourvehicle'sbattery.
• Checkclearancesonbothsidesofaplannedmountingsurfacebeforedrillinganyholesor
 installinganyscrews.Rememberthatthescrewscanextendbehindthesurface.
• Attheinstallationsites,locateandmakeanoteofallfuellines,hydraulicbrakelines, 
 vacuumlines,andelectricalwiring.Useextremecautionwhencuttingordrillingin 
and around these areas.
• Beforedrillingofcuttingholes,useautilityknifetoremoveunwantedfabricorvinylto 
 keepmaterialfromsnagginginadrillbit.
• Whenroutingcables,keepinput-signalcablesawayfrompowercablesandspeakerwires.
• Whenmakingconnections,makecertaintheyaresecureandproperlyinsulated.Ifthe 
 amplifier'sfusemustbereplaced,useonlythesametypeandratingasthatoftheoriginal.
 Donotsubstituteanotherkind.

CHOOSING A LOCATION AND MOUNTING THE AMPLIFIER
Amplifiersneedairtostaycool.Suitablelocationsinthecreworcontrolcabin(providedthe
amplifierdoesn'tinterferewithdrivingmechanism)orinanyotherlocationwhichprovides
enoughairfortheamptocoolitself.Fortheheatsinkoftheamplifieronthebothside,Note
convectioncoolingofthebothheatsink,andkeepthebottomortopoftheamplifierno-touching
any fabric or vinyl material.
Mounting Dimensions
Mount the amplifier so that it is not damaged by the feet of passengers or shifting cargo in the
crew cabin. Mount the amplifier so that it remains dry never mount an
amplifieroutsidetheboatorintheenginecompartment.Usingtheamplifierasatemplate,mark
the location of the mounting holes on the mounting surface, drill pilot holes,
andattachtheamplifiertothemountingsurfacewithscrews.Makesuretheamplifieris
mounted securely.

POWER CONNECTIONS
TheB52marineamplifiersarecapableofdeliveringextremelyhighpowerlevels,andrequire
aheavy-dutyandreliableconnectiontothevehicle'selectricalsysteminordertoperform
optimally.Pleaseadheretothefollowinginstructionscarefully:
Ground Connection
Connecttheamplifier'sGround(GND)terminaltoasolidpointonthevesselmetalchassis,as
close to the amplifier as possible. Refer to the chart below to determine minimum wire-gauge
size.Scrapeawayanypaintfromthislocation;useastar-typelockwashertosecurethe
connection.
Power Connection
Connectawire(seechartatrightforappropriategauge)directlytothevehicle'spositivebattery
terminal,andinstallanappropriatefuseholderwithin18"ofthebatteryterminal.Donotinstall
thefuseatthistime.Routethewiretotheamplifier'slocation,andconnectittotheamplifier's
Positive(BATT+)terminal.Besuretouseappropriategrommetswheneverroutingwiresthrough
the firewall or other sheet metal. Failure to adequately protect the positive wire from potential
damage may result in a vehicle fire. When you are done routing and connecting this wire, you
may install the fuse at the battery.
Remote connection
Connecttheamplifier'sRemote(REM)terminaltothesourceunit'sRemoteTurnOnleadusinga
minimumof18-gaugewire.
Speaker Connections
Refertotheapplicationguidesonthepagesthatfollow.Speakerconnectionsshouldbemade
using a wire as per the following chart instructions.
Wire Gauge Chart
PowerCable 6-guage (4mm2)
SpeakerWire 12-gauge(2mm2)
RemoteWire 18-gauge(1mm2)
SignalCable 8-gauge (3mm2)

CONTROL FUNCTIONS

1. RCA inputs
RCAcablesmarkedFRONTorREARfromheadunitorotherlineleveldeviceshouldbe
connectedhere.Usebothinputs(L&R)forfrontandrearstereo.
2. Input Level Controls
This is for adjusting input sensitivities. To adjust the sensitivity, turn the controls fully
counterclockwisetominimum.Adjusttheradio/headunitvolumeknobtomaximumvolume,
andthenturnthelevelcontrolsontheamplifierclockwiseuntilaudibledistortionoccurs.
3. Crossover Selector (HPF/FLAT/LPF)
This switch allows these two amplifier channels to play full range, low pass, or high pass. In
theLPF(LowPassFilter)position,allthehighfrequenciesarefilteredoutandtheamplifier
produces only low bass frequencies.
On the contrary, in the HPF position, the low frequencies are filtered out and allowing the
amplifier to play mid and high frequency. If the amplifier is used to power subwoofers, set the
crossoverswitchtoLPF.Iftheamplifierisusedtopowermidrangeandtweetersorcoaxialtype
speakers,setthecrossovertoHPF.
Switch the crossover to FLAT when amplifier is used in Tri mode configuration or when full
rangespeakerareused.
4. Status LED indicators
BLUEindicatesthenormaloperatingcondition:theamplifierisON.

CONTROL FUNCTIONS
5. CORSSOVER
ThisisforadjustingLPF&HPFfrequencies;IntheLPFposition,toadjustthefrequenciesfrom
32Hz-320Hz,allthehighfrequenciesarefilteredoutandtheamplifierproducesonlylowbass
frequencies.IntheHPFpositiontoadjustthefrequenciesfrom32Hz-320Hz,thelowfrequencies
are filtered out and allowing the amplifier to play mid and high frequency.
6. Bass Boost
Thisisforadjustinginputsignalbassboostlevelal50Hz,turnthecontrolsbassboostlevel,at
0dBto+6dB.
7. Speaker Terminals
Itallowstheconnectionofspeakerstotheamplifier.Notethepolarofthespeakers.
8. Ground Connector
It connects GND wire from a connection point on the vehicle chassis.
9. REMOTE control
This connects the control wire switch allows the amplifier to be turned on and off by the head unit.
10. Power Connection
Itconnects+12VDCpowerwirefromthebattery.
